**Gas in a bulb.**  If you look closely you can see the pale green-yellow tint created by the approximately 1 atm pressure of chlorine gas in this sealed bulb. There's a very similar bulb under [|bromine], but its color is much, much darker. Normally when you see a "gas" that is colored, it's not really a gas but rather tiny droplets of liquid (in fog) or particles (in smoke) that make it look colored or thick. The difference is that in a real colored gas, there is no diffusion of the light, just attenuation. A fog or smoke makes things look fuzzy, while with a true colored gas, they look perfectly sharp, just colored. I received this sample when Tryggvi and Timothy came to my [|sodium party].



**Clorox bleach.**  Shouldn't that be Chlorox, if it's chlorine bleach? Anyway, this is common sodium hypochlorite household bleach, an example of one of the most common applications of chlorine, as a disinfectant and oxidative cleaner.
